ELECTRIC SWITCH-BOX.

To all whom it may concern:

Be it known that I, LLOYD B. HORNBECK, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful' box having a cover capable of adjustment on the box to adapt it for use with a vertically arranged push button plate or with onev that is horizontally arranged.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claim.

In the accompanying drawings forming part of this specification, Figure 1 is a front view of a switch box embodying my invention, Fig. 2 is a transverse, sectional view of the same, Fig. 3 is a sectional view showl ing the box mounted in the wall, Fig. 4 is an outside view, Fig. 5v isa detail sectional view of a modified construction. In the drawings, 2 represents a switch b o having the usual removable disks 3 covering holes through which pipes 4 arevinserted to contain the cables 5. A cover 6 has aflange 7 secured to the box 2 by-screws 8, the walls of said cover converging, yas indicated in Fig. 3, and forming with the flange 9 at the outer end of said cover a recess 10 to receive the ends of the lath 11. This cover is capable. of adjustment on the box to adapt it for a vertical or horizontal arrangement of the push button plate. Generally the box and cover willbe arranged as in Fig. 1, but the position of the cover can be changed so that the plate will extend horizontally. The ends of the lath are preferably held in place between the converging walls of the cover and the flange 9, against which walls the ends of thelath are seated. The box is -sometimes set into the wall or partition a considerable distance, so that an ordinary cover would not extend to the surface of the plastering. I preferl to provide, therefore, a telescoping section 13 fitting within the cover 6 and capable of sliding back and forth therein and having a recess wherein the push button switch 14, of ordinary con- Specication of Letters Patent.

struction, is inserted. This telescoping section has a flanged outer ortion 15 to rest upon the plastering or p aster, being held between the flanges of the ncover and the telescoping section. Evidently, this telescoping 'section can be moved in and out to adapt it to the thickness of the plaster and to the position of the box in the wall. The telescoping section is made adjustable by means of the screws 12 which pass through the flanges 15 and 9.

In Fig.- 5 I have shown a modified construction, which consists in providing a box 16 having a removable flange 17 and a telescoping part 18 corresponding to the one described, and adapted to be clamped to the lath and plaster by screws in the same man` ner as shown in Figs. -2 and 3. The de vice may be made in any suitable size according to the number of switches to be used, and the attachments herein shown may apply to any style of switch box ingeneral use.

I claim as my invention The` combination, with a wall switch box, of a cover adapted to lit over the open face of said box and having a anged inner end and means securing it to the walls of said box, said cover having converging side and end walls terminating at their outer edges in an outwardly extending flange, a Seat being formedA between said flange and the walls of said cover to receive the lath, the ends of the lath being concealed by said 4flange, said cover having an opening therein encircled by said last named liange, a flanged sleeve iitting within said opening, adjusting screws .passing through the outer flange of said cover and the iange of said sleeve for moving said sleeve back and forth in said cover opening, the space between the outer flange of said cover and the flange of said sleeve being adapted to receive the plastering, and the adjustment of said sleeve adapting it to plastering of different thickness, and a switch fitting within said sleeve and having an outer face plate covering and concealing the flange of said sleeve, substantially as described. e

In witness whereof, I have hereunto set my hand this 4th day of November, 1910.` LLOYD B. HORNBECK.
